1. 流動相的準備為了防止顆粒性物質對泵組件的磨損，流動相（特別是水相）應該新鮮配置並且過濾。上機前對流動相進行適當的超聲脫氣，以保證更好的在線脫氣和在線混合的效果。

 

2.比例閥溶劑通道的分配四元泵的比例閥有A、B、C、D四個通道

，建議將鹽溶液接在下麵的通道（A或D）


，將有機溶劑接在上麵的通道（B 或C）上,也就是有機通道最好在鹽溶液通道的上麵。且建議用水定期衝洗所有比例閥通道除去可能在閥口析出的鹽結晶。

，如果泵壓超過10bar，則說明過濾白頭需要更換了。對過濾白頭的預防性維護通常可以是1~2個月更換1次

，更換時同時檢查一下過濾白頭前麵的密封金墊，如果發現變形
，也應及時更換。 如(ru)果(guo)過(guo)濾(lv)白(bai)頭(tou)更(geng)換(huan)過(guo)於(yu)頻(pin)繁(fan)
